类比的能力需要两个关键的认知过程，关系整合和干扰的解决。本研究的目的是确定一个单一的，非言语类比任务中，使用事件相关功能磁共振成像的类比推理的两个组件过程的神经相关。参与者验证是否是真实的视觉类比考虑1或3个关系维度。在一半的审判中，为了做出正确的判断，还需要解决干扰问题。要整合的维度数量的增加与两个半球的外侧前额叶皮层和外侧额极的激活增加有关。当需要解决推理过程中的干扰时，外侧前额叶皮层的激活增加，但额极没有。我们确定的区域中，额下回是专门敏感的要求，每个组件的过程中，除了这些神经相关的每个组件的过程之间的部分重叠。这些结果表明，类比推理是介导的协调多个区域的前额叶皮层，其中一些是敏感的要求，只有一个这两个组件的过程，而其他人都敏感。
The ability to draw analogies requires 2 key cognitive processes, relational integration and resolution of interference. The present study aimed to identify the neural correlates of both component processes of analogical reasoning within a single, nonverbal analogy task using event-related functional magnetic resonance imaging. Participants verified whether a visual analogy was true by considering either 1 or 3 relational dimensions. On half of the trials, there was an additional need to resolve interference in order to make a correct judgment. Increase in the number of dimensions to integrate was associated with increased activation in the lateral prefrontal cortex as well as lateral frontal pole in both hemispheres. When there was a need to resolve interference during reasoning, activation increased in the lateral prefrontal cortex but not in the frontal pole. We identified regions in the middle and inferior frontal gyri which were exclusively sensitive to demands on each component process, in addition to a partial overlap between these neural correlates of each component process. These results indicate that analogical reasoning is mediated by the coordination of multiple regions of the prefrontal cortex, of which some are sensitive to demands on only one of these 2 component processes, whereas others are sensitive to both.
